Philospher Stone

The Philospher Stone is a material. The game states that it is "Extremely sought-after by alchemists who want to make something boring, like gold."

Robes
Description: A percentage of incoming damage is taken from mana instead of health.

The player will show a purple "Resist" text effect when damage was reduced by mana, similar to the Quiver's damage resistance effect. If the player's mana is too low, excess damage after being reduced goes straight to the player.

The maximum Mana Shield is 99%, which can be achieved by slotting 1 Grade A Philospher Stone onto the robe.

Spells
Description: Consumes extra mana to boost spellpower.

Fractional mana costs are correctly accounted for in-game, though they will still appear to be rounded down in UIs.
